Abstract

The invention discloses a method and a system for acquiring a critical electricity price of a project, and relates to the technical field of land wind power projects. Through a data fitting method, the relation between the critical electricity price DJi and the unit electricity degree investment DT when the return rate is i is obtained, and the relation between the critical electricity price DJi and the unit electricity degree investment DT is suitable for various land wind power projects. According to the system for acquiring the critical electricity price DJi when the project yield is i, the data acquisition module and the data processing module do not need to work during calculation every time and can be set to work once every time interval T, work of the data acquisition module and the data processing module can also be started according to actual needs, and therefore the work efficiency of the data acquisition module and the data processing module is improved. Therefore, the calculation amount is reduced, the calculation time is also reduced, and the calculation efficiency is remarkably improved, so that the critical electricity price DJi corresponding to different return rates i of the current project can be quickly and intuitively obtained.

Description

technical field [0001] The invention relates to the technical field of onshore wind power projects, in particular to a method and system for obtaining critical electricity prices of projects. Background technique [0002] In recent years, with the development of new energy, wind power has entered a stage of high-speed, high-quality sustainable development. The arrival of the era of wind power parity and low price has forced the entire industry to reduce costs and increase efficiency, bringing challenges to the industry, but also Improve the competitiveness of wind power. Wind power investment enterprises are most concerned about the project investment income during the early stage of the project. Only when the project capital return rate is greater than the benchmark return rate or the critical electricity price is lower than the actual electricity price, the project is feasible. [0003] At present, the calculation method for the return on capital of onshore wind power pro...
